Instance crashes

Had 2 instance crashes.
One was L80 Logbook.

The other was a T15 map with 6? affixes.
Steaming Springs node with a Delirium, Map Boss, Irradiated addons.

coincidentally, the addons were gone after restarting.

also.. instances crashed ~20-30 secands after entering.

Crashing all the time after the patch.

Maps still crashing and losing the map progress even after fix.

Lost an arbiter fight :(

Crashing mid-map every ~1 in 10 maps, kicked out to login screen with "disconnected from server" and when I come back into my hideout portals are gone. Please fix this, it's really really broken. I'm losing a lot of time and effort to create good map instances and losing them to these instance crashes paired with an unnecessarily unforgiving instance shutdown/forfeiting. I'm also seeing maps frequently fail to open portals, and random disconnects in my hideout when trading (seemingly also happens to the other player)

I'm on Texas servers, this seems like a server-side issue.

Texas server as well

Same issue, Texas servers. I had just picked up a div :((((
